You might find Cederstrand on the high side. Contact Mike at Muscle Motors. They have some very affordable packages. I actually have their 528 HEMI in my 69 Charger R/T. Give them a call.
Ive gotten their ignition system and a mighty demon 750 quite a few years back and don was extremely helpful. The parts were top notch also...never a single problem. I would use them again!
